CAP-CLOSUBE FOR BOTTLES.

Specification of Letters Patent.

Patented ldey 26, 1908.

Application tiled April 29, 1907. Serial No. 370,842.

. Be it known that i, Grs'rev. Koen, citizen of the United States, residing at New York; in the countyof N ew York and State oi N ew York, have lnvented certain new and useful Improvements in Cap-Closures for Bott-lcs, of which the following is a specification. l

- M invention relates to cap closures for bottes, and belongs to that class, exam iles of which are provided with a yielding dis of suitable material, usually cork, which is located within the cap and is pressed down upon the to of the bottle and held in position by ben ing a portion of the cap Vbeneath an extending rim or the like formed integral.

with the Vbottle.

The object of my invention is the production of a cap for the purpose and of the nature stated, having special construction, and which may be'released and removed from the bottle without the aid of a particular tool, and,'in many instances, the cap is detachable with the ngers and no tool of any description iskneeded.`

"I accomplish the ob'cct stated by fashioning my invention in tlie form illustrated in the accompanying drawings. of which i Figure vl represents the neck ol a bottle with the ca set over the top. In this view the metal o the cap is not bent and the cap is not secured to the bottle. Fig. 2 is a vertical section of the neck of a bottle and the cap constituting my invention. Tn'this view the metal of the cap is shown inwardly bent and the bottle closed. Fig. 3 is' a representation of the neck oi a bottle with the cap made in ence with-roy invention set upon it rned one-quarter way round from the iig. 4 is a vertical cross-section of part of the neck of a bottle and the cap in the positions shown in Fig. 3.

Like reference letters are employed to designate the same parts throughout. the specification and claims.

The neck A. of the bottle is formed with the customary annular rim a or in other desired p shape.

I construct a cap B having its lower edge provided with a plurality of downwardly and outwardly projecting portions C. Through the wall of the cap, for example, at substantially e ual dista nces apart slots l) are formed,`

the orifices E as part thereof, the edges of the slot are to a greater extent'and much more easily bent `inwardly, because, only those edges are affected. Without the orifices E, any attempt to bend the edges oi" the slot inwardly to any extent results in tearing the adjoining metal, and the'iorcc required is much greater' than is the'condition with the orifices included.

The yielding or cork disk contained within the cepis marked, F.

To operate my invention the ca is res downwardly upon the top of the ottie, the cork diskcompressed as shown in Fig. The metal of the cap at the sides of the siots bis then forced inwardly beneath the rima, which serves tor holdthe cap u on the bottle and the cdiki disk eiicctua y in consct therewith. cient to Tess outwardly rind upwardly upon either o the projecting nortions C. may be done by means oi any utensil conveniently accessible ,at the time-"e, pocket knife or the end of a stickwpracticaiiy any article may accomplish the purpose, and it is not at all a dii'iicult matter to detach lthe cap in many instances sim ly with the lingers, by reason of the specie construction above set forth.

Havin now described my invention and explained the inode of its operation, i claim is- ,1. A Vcap closure having slots formed through its wall, the said slots opening at their .ends into Aorifices et iarger diameter than the width of the slot, andthe edges of the slots between the said orifices adapted to be .bent inwardly beneath the riin of a This Toremore the cap it is suiibottle to secure the cap, substantially vas orifices of larger diameter than t th of the ein s oi the slot opening into the larger i the slot., and the edges of the slots between circular orifices E.'
